Study Notes
Mechanical Digestion
- Refers to the physical breakdown of large food pieces into smaller fragments.
- Initial step occurs in the mouth through mastication (chewing).
- Takes place in the small intestine via segmentation contractions, enhancing food movement and mixing.
Chemical Digestion
- Involves the use of enzymes to degrade food into smaller, usable compounds.
- Transforms large insoluble food compounds into small, water-soluble components for absorption.
Overall Digestion Process
- Begins when food enters the digestive system.
- Mechanical digestion aids in preparing food for chemical digestion by increasing surface area for enzyme action.
- Resulting small water-soluble components can be absorbed into blood plasma for nutrition.
